Some 30 people have been killed and 80 others injured as three suicide bombers attacked the island of Koulfoua on the Chadian side of Lake Chad, Reuters reports, citing security sources. The attacks coincided with market day and the death toll may rise. “Three suicide bombers blew themselves up in three different places at the weekly market on Loulou Fou, an island in Lake Chad,” sources also told AFP. No one has yet claimed responsibility for the attacks.

However, the the region is under a state of emergency after attacks by Boko Haram militant group. Earlier this year, thousands of people fleeing the militant group sought refuge on the island.

The State Department has warned of an imminent security threat to the US consulate in the Turkish city of Istanbul, urging American citizens to avoid the area. OSAC also encouraged American citizens in Turkey “to maintain a high level of vigilance, be aware of local events, and take the appropriate steps to bolster your personal security.”

A major fire has broken out on an offshore oil platform in Azerbaijan’s waters. While no official casualty count was immediately available, an independent report indicated that the disaster claimed 32 lives. The ongoing rescue operation is hampered by stormy weather with waves rising up to 11 meters high, the Trend news website reported.

The fire started overnight at a rig at the Gunashli field southeast of Neft Daşları (Oil Rocks) settlement. It was caused by strong winds that damaged a gas pipeline on the platform, the Azeri state energy company SOCAR said.
